Abstract
The copy master is illuminated in scanning sections located along scanning lines and measuring light coming from the scanning sections of a scanning line is spectrally decomposed and subsequently passed onto a photoreceiver line coordinated with the scanning line involved. Along this photoreceiver line photoreceiver groups sequentially follow each other, each group being assigned to the spectrum of a scanning section of the scanning line involved.
